Don't waste your time with these folks. Customer service is shoddy at best; they are unable to keep the product in stock, and a subscription is useless because they won't have the product availab... See more

Excellent product, service and cause

Ordered directly from Kill Cliff. Fast and free shipping! I love to drink this during and after a workout to maintain hydration and help my recovery. It is a relatively clean drink that also supports a cause that is very important to me.

To be honest I was skeptical

To be honest I was skeptical, I've tried enough products to know they generally do not do what they say. If they they do help performance, there is something that makes them unpleasant, like caffine, flushed skin, tingling etc. But, after a nine mile run for distance and the next day an 5 mile run with hills, the product did exactly what it claimed - no quit. I ran with pleasure - not missing the normal low gut feeling of not wanting to keep running. I will be using these products this year for two Spartan Trifectas.

Double Awesomeness

Received the email to write a review before I even wore the shirt... I can now say that I have worn the shirt and...

Hit a 30# PR on my sumo deadlift 3 rep max...? Must be my new KC shirt! Two of my favorite brands collaborating for one epic shirt... Can’t wait to see what happens when I wear the tank!

Seriously though, the shirt fits as expected. Proud to support these two spectacular brands. ❤️

Reply from Kill Cliff

Glad you're such a fan!! We're pretty fond of them too ;)

Good news is that you will see them in more retailers going forward but for now you can still order on our website, where we offer 12pks and cases, and we provide free shipping to anywhere in the continental US!! Reach out to us at customerservice@killcliff.com if you have any questions or we can help!

Your website is so slow

Your website is so slow, it took me nearly a full workday to order a shirt. I'm sure the shirt will be 5 stars, but it's worth a few more dollars a month to upgrade the server so customers can make orders in a timely manner.

Product is worth the price.

The product is a little pricey, but for the quality and free shipping I have no problem ordering more. The recovery drinks are top of the line!!!!

I bring KC regular and Endure on hunts

I bring KC regular and Endure on hunts, range training days, and just plain old PT days. My clients love it and I love it. K. Leng is my go to rep. Call her and get set up if you're a business. She's on top of it.
